   Engineering standard: matches Atamap Associates rebuild
   Stack: vanilla CSS (no preprocessor, no framework)
   Foundations:
     - 8pt grid for all spacing
     - iOS-style squircle corners (SVG mask superellipse, not border-radius)
     - SF Pro-derived type scale with system font fallback
     - Apple-calibrated spring motion (cubic-bezier easings tuned to iOS feel)
     - Subtle mesh gradient on white background (pale horse-red washes)
     - Light UI with glassmorphism + horse-red accent (from the brand logo)
